Spansion LLC, the Flash memory venture of AMD and Fujitsu Ltd, announced it is sampling what it touts as the world's first single-chip 1Gb NOR flash memory device to customers in the embedded market. Based on Spansion's 90nm mirrorbit technology, the 1Gb MirrorBit GL device is one of the highest density, single-chip NOR Flash memory device on the market. This device is designed for reliable code execution and data storage in a wide range of embedded applications, including automotive navigation systems, communications infrastructure equipment, gaming and industrial control.

"Our innovative MirrorBit technology has enabled us to reach this very important milestone, with a product that meets the density, quality, cost structure and scalability needs of the diverse embedded market," said Ian Williams, corporate vice president of marketing for the Embedded Memory Division for Spansion. "High density single-chip NOR Flash memory products help customers lower their design cost, enhance end product features, and ensure reliable, fast code execution. In addition, with this added storage capacity, customers can leverage a single chip for both code execution and data storage."

The 1Gb MirrorBit GL device extends the MirrorBit GL family, which also includes a single-chip 512Mb NOR flash memory device. By scaling MirrorBit technology to 90nm and doubling the density of its NOR flash memory, the company was able to reduce component costs because it enables customers to use a single-chip device, instead of multiple lower density discrete solutions or more costly multi-chip packages containing stacked lower density die. Moreover, as an extension of its existing embedded product families, the device allows customers to easily migrate to new high-density solutions, without having to engage in costly and complex system redesign.

The 1Gb MirrorBit GL operates at 3Vcc, features a random read speed of 110ns, and offers a page read speed of 25ns via an 8-word page buffer. This product enables users to either execute code directly out of the flash memory or shadow into DRAM at high speeds. It supports industrial temperature ranges from -40°C to 85°C. In addition, the new 1Gb MirrorBit GL uses a NOR architecture that is designed to deliver 100 percent good sectors, eliminates the need for ECC and supports a standard parallel interface, reducing system complexity and cost.

For applications requiring advanced security, Spansion supports Advanced Sector Protection (ASP) technology on the 1Gb MirrorBit GL. ASP provides robust and complete designer-defined security with 64-bit password protection for sensitive software algorithms or parameters. This feature can be used by designers to store, lock and protect code or data stored on any sector of the device, or assign an electronic serial number to their product.

The part number for the 1Gb MirrorBit GL is S29GL01GP. This product is offered in 56-pin TSOP and 64-ball Fortified BGA packaging. It will be priced at approximately $18.50 in quantities of 10,000. The 1Gb MirrorBit GL is package and pin-out compatible with all MirrorBit GL-M (230nm), MirrorBit GL-A (200nm) and MirrorBit GL-N (110nm) devices, as well as legacy Fujitsu and AMD LV family members (back to the 320nm lithography). Packaging is JEDEC-compliant, and production is slated to begin in late Q4.
